♠ Umugqa wokufinyelela we-ultra-low-power 32-bit MCU Arm®-based Cortex®-M0+, kufika ku-64 KB Flash, 8 KB SRAM, 2 KB EEPROM, ADC
Ulayini wokufinyelela we-ultra-low-power STM32L051x6/8 microcontrollers ihlanganisa ukusebenza okuphezulu kwe-Arm Cortex-M0+ 32-bit RISC core esebenza kumafrikhwensi angama-32 MHz, inkumbulo.iyunithi yokuvikela (MPU), izinkumbulo ezishumekwe ngesivinini esiphezulu (64 Kbytes of Uhlelo lwe-Flashinkumbulo, ama-Kbytes angu-2 wedatha ye-EEPROM kanye no-8 Kbytes we-RAM) kanye nobubanzi obubanzi beama-I/O nama-peripheral athuthukisiwe.
Amadivayisi we-STM32L051x6/8 ahlinzeka ngokusebenza kahle kwamandla okuhlukahlukeneukusebenza. Ifezwa ngokukhetha okukhulu kwemithombo yewashi yangaphakathi neyangaphandle, iukujwayela i-voltage yangaphakathi kanye nezindlela ezimbalwa zamandla aphansi.
Amadivayisi we-STM32L051x6/8 anikela ngezici ezimbalwa ze-analog, i-12-bit ADC eyodwa ene-hardware.amasampula amaningi, izifanisi ezimbili zamandla aphansi kakhulu, izibali sikhathi ezimbalwa, isibali-sikhathi samandla aphansi esisodwa(LPTIM), izibali-sikhathi ezintathu zenhloso evamile engu-16-bit kanye nesibali sikhathi esisodwa esiyisisekelo, i-RTC eyodwa neyodwaSysTick engasetshenziswa njengezisekelo zesikhathi. Baphinde bafake nezinja ezimbili, inja eyodwa yokubukangewashi elizimele kanye nekhono lewindi kanye ne-watchdog eyodwa yewindi esekelwe ebhasiniiwashi.
Ngaphezu kwalokho, amadivayisi we-STM32L051x6/8 ashumeka ukuxhumana okujwayelekile nokuthuthukileizindawo zokuhlangana: kufika kuma-I2C amabili, ama-SPI amabili, i-I2S eyodwa, ama-USART amabili, i-UART enamandla aphansi (LPUART), .
I-STM32L051x6/8 ihlanganisa newashi lesikhathi sangempela kanye nesethi yamarejista asekelayohlala unamandla kumodi yokulinda.
Amadivayisi anamandla aphansi kakhulu e-STM32L051x6/8 asebenza kusuka kugesi ongu-1.8 kuye ku-3.6 V(yehle ifike ku-1.65 V ngogesi wehla) nge-BOR futhi isuka ku-1.65 kuya ku-3.6 V kagesi ngaphandleInketho ye-BOR. Atholakala ebangeni lokushisa -40 kuya +125 °C. A olunzuluisethi yamamodi okonga amandla ivumela ukuklanywa kwezinhlelo zokusebenza zamandla aphansi.
